Abstract
The utility model relates to a structure of miniature piles in combination with a composite soil nailing wall, comprising an excavation slope. The structure is characterized in that a surface concrete layer is poured on the side wall of the excavation slope; a soil nailing wall reinforcing mesh is built in the surface concrete layer; a plurality of anchor bars extending into the excavation slope are further arranged on the side wall of the excavation slope; and miniature steel pipe piles are vertically arranged in the excavation slope. In order to guarantee the stability of the steep or even vertical excavation slope, while the surface concrete layer and the anchor bars are arranged, the prefabricated miniature steel pipe piles are added to play the role of supporting; and the structure does not occupy a field and is flexible to operate.
Description
Technical field
The utility model relates to a kind of building foundation pit slope reinforcement structure, and particularly a kind of suitable on-the-spot place is narrow and small, side slope is steep and mini pile that foundation depth is not dark combines composite soil nailing wall structure.
Background technology
Excavation slope need carry out support reinforcement under construction, avoids toppling.Present excavation slope is reinforced and all relatively is fit to foundation ditch large-scale and that on-the-spot place is broad.Also unspecial narrow and small to this on-the-spot place, the steep and not dark situation of foundation depth of side slope.
Summary of the invention
The technical problem that the utility model will solve provides the mini pile combination composite soil nailing wall structure that a kind of suitable on-the-spot place is narrow and small, side slope is steep and foundation depth is not dark.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of mini pile combines composite soil nailing wall structure; Comprise excavation slope; Its innovative point is: said excavation slope sidewall is built the facing concrete layer, and the built-in soil nailing wall of said facing concrete layer steel mesh reinforcement, excavation slope sidewall also are provided with some dowels that stretch in the excavation slope; Be vertically installed with miniature steel pipe pile in the said excavation slope.
Further, said dowel diameter is φ 16--32mm, the 0.5--1.2 that length is preferably foundation depth doubly, spacing is 1--2m, is preferably 5o-20 ° with the angle of horizontal plane.
Further, said miniature steel pipe pile is that φ is more than 130.
The advantage of the utility model is: in order to guarantee the stability of the precipitous even vertical side slope of excavation slope, when facing concrete layer, dowel are set, increase prefabricated miniature steel pipe pile and can play good supporting role, and occupied ground not, flexible operation.
Description of drawings
Fig. 1 combines the composite soil nailing wall structure sketch map for the utility model mini pile.
Fig. 2 is the partial enlarged drawing of Fig. 1.
The specific embodiment
Like Fig. 1, shown in 2, comprise excavation slope 1, excavation slope 1 sidewall is built facing concrete layer 2; Facing concrete layer 2 built-in soil nailing wall steel mesh reinforcement 3; Excavation slope 1 sidewall also is provided with some dowels 4 that stretch in the excavation slope, and the dowel diameter is φ 16--32mm, and length is preferably 0.5--1.2 times of foundation depth; Spacing is 1--2m, is preferably 5o-20 ° with the angle of horizontal plane.In addition, in excavation slope 1, be vertically installed with miniature steel pipe pile 5, the diameter of miniature steel pipe pile 5 is that φ is more than 130.
